SERVOSTAR-670

Product Description

The SERVOSTAR-670 is an electric servo control developed for diverse industrial applications which require precise control of an electric motor. In addition, the possibilities of the offered devices ensure their smooth operation and high reliability. It accepts a differential input voltage of ~ 10 V relative to the ground at the terminal X3/7 and has an input resistance of 2.4 k1/2. Operation is maintained as long as the common mode voltage level is ~ 10 V and has an impressive update rate of 62.5 us, hence control is relatively accurate and responsive.

Thermal protection of the servo-amplifier and the servo motor loaded with drives is done with PTC (positive temperature coefficient) which extends into the motor windings. The embedded thermal devices implement a thermal cut-off for the parameters of the amplifier and motor preventing working temperatures from exceeding safe values. Another notable feature of this amplifier is Tn, I-integration time is included in the control loop making it easy to fine-tune the performance of the motor in question. This feature makes the SSI-interface very useful in applications where precision in motion or positioning techniques is needed since it provides serially cyclically absolute position outputs.

Constant operation of a motor is achieved by the fact that the setpoint ramps feature limits the acceleration rate to a particular speed setpoint in order to avoid any steeper accelerations or deceleration that could bring some level of instability in the system. The capacity of the amplifier also includes the use of passive conduction which makes use of circulating air without the use of an internal fan to cool temperatures. With no movement of the fan, the internal temperature does not exceed 55 degrees C while the heat sink temperature does not exceed 60 degrees C.
